e^{ix} = cos(x) + i*sin(x)
Exponential functions and trigonometric functions.
From infinite series expansions of e^x, cos(x), sin(x).
It separates real and imaginary parts in complex numbers.
z = re^{iθ}, where r is modulus and θ is argument.
Use r = √(x² + y²) and θ = tan⁻¹(y/x).
It rotates complex numbers in the complex plane.
6 e^{i(5π/12)} in polar form.
It links Euler's formula to key mathematical constants.
It helps break down complex waveforms into components.
